Good Molecules Hyaluronic Acid Serum
Formulation Summary
An ultra-minimalist hyaluronic acid serum with only eight ingredients. The formula delivers sodium hyaluronate and panthenol in a clean, no-frills base. No fragrance, no oils, no silicones, no unnecessary additives. Designed as a pure hydration step that works with any routine.
Good Molecules takes a deliberately minimalist approach with just eight ingredients. Sodium hyaluronate is listed second after water, indicating it is the primary functional ingredient. Panthenol provides soothing and moisture-attracting support. Propanediol serves as the solvent and humectant. Hydroxyethylcellulose provides the gel texture. The formula strips away everything that is not directly serving hydration. No fragrance, no silicones, no oils, no fatty alcohols.

The Formulation Explained
Eight ingredients total
With only eight ingredients, this is one of the most minimal serums available commercially. Each ingredient serves a clear purpose: water as the solvent, sodium hyaluronate for hydration, panthenol for soothing, propanediol as a co-solvent, hydroxyethylcellulose for texture, sodium hydroxide for pH adjustment, and two preservatives. Nothing is decorative or marketing-driven.
No frills hydration
The formula excludes fragrance, silicones, oils, fatty alcohols, niacinamide, and botanical extracts. This makes it one of the safest options for extremely sensitive or reactive skin. The trade-off is a basic texture and no secondary benefits beyond hydration and soothing.
Price-to-performance ratio
At $6 for 30ml, this serum delivers sodium hyaluronate and panthenol at a fraction of the cost of comparable products. The minimal formula means lower production costs. For users who only need hydration, this removes the premium paid for marketing ingredients or luxury textures.
Ingredients to Know
Plant-derived solvent and humectant. A gentler alternative to propylene glycol. Listed fourth.
Plant-derived thickener that creates the gel texture. Completely inert and non-irritating.
Preservative. Widely used and well tolerated. Present at the standard low concentration needed to keep the product safe.
